The copyright assignment applicable law is therefore the law of the contract, not the law of each country where protection is claimed. It matters to any company acquiring rights from authors abroad.<\/p>\n<h2>Key takeaways<\/h2>\n<ul>\n<li>The CJEU (Third Chamber, judgment of 24 September 2026) held that formal validity of an assignment of exclusive rights of use is a <strong>contractual matter under Rome I<\/strong>, not a non-contractual matter under Rome II.<\/li>\n<li>The infringement itself remains governed by the law of the country for which protection is claimed (Rome II, Article 8(1)).<\/li>\n<li>The law of the contract also decides the consequences of a formally invalid assignment, including whether the assignee holds the rights.<\/li>\n<li>Choosing the governing law and signing in writing are now the simplest ways to secure an assignment across borders.<\/li>\n<\/ul>\n<h2>What did the CJEU decide in Steizer?<\/h2>\n<p>According to the <a href=\"https:\/\/eur-lex.europa.eu\/legal-content\/EN\/TXT\/?uri=CELEX:62025CJ0176\" target=\"_blank\" rel=\"noopener\">judgment in Case C-176\/25<\/a> (ECLI:EU:C:2026:785), a German online seller of car floor mats hired a Polish photographer between 2014 and 2018 on the basis of oral agreements. The photos were taken in his studio in Poland and handed over on a USB stick. Nothing was signed, and no governing law was agreed. When a competitor reused some of the photos on eBay, the seller sued in Germany.<\/p>\n<p>The competitor argued that the assignment was governed by Polish law, which in its submission requires exclusive rights to be assigned in writing, so the seller had no standing. The seller argued for German law as the law of the country of protection, which in her submission imposes no formal requirement. The Higher Regional Court of D\u00fcsseldorf asked the CJEU which regulation decides.<\/p>\n<p>The Court answered that, in an infringement action by a third party, the formal validity of the assignment between the claimant and the author is a contractual matter, so the applicable law must be determined under Rome I. Advocate General Emiliou had reached the same conclusion in his Opinion of 23 April 2026.<\/p>\n<h2>Why Rome I and not the law of the country of protection?<\/h2>\n<ul>\n<li>Form is about consent. Formal requirements exist to show that the parties freely agreed to be bound, which is the definition of a contractual obligation (paragraph 46).<\/li>\n<li>Legal certainty. One contract law gives assignor and assignee a predictable answer, whereas the law of the country of protection could produce a different answer in every Member State where an infringement occurs (paragraph 47).<\/li>\n<li>No impact on the substance of copyright. The Court rejected the European Commission&#8217;s view that form is linked to ownership: the question does not concern protectability, authorship or scope of protection (paragraphs 48 to 51).<\/li>\n<li>Consequences of nullity follow the contract. Under Article 12(1)(e) Rome I, the law of the contract decides whether the assignee of a formally invalid contract holds the rights (paragraph 53).<\/li>\n<\/ul>\n<p>Territoriality survives: national copyright laws still govern protection, and the infringement is still assessed under the law of the country of protection (paragraphs 54 and 55).<\/p>\n<h2>How Rome I determines the copyright assignment applicable law<\/h2>\n<p>The <a href=\"https:\/\/eur-lex.europa.eu\/eli\/reg\/2008\/593\/oj\" target=\"_blank\" rel=\"noopener\">Rome I Regulation<\/a> applies whichever law it designates, including the law of a non-EU country (Article 2). The rules that matter for assignments are:<\/p>\n<table>\n<thead>\n<tr>\n<th>Situation<\/th>\n<th>Rule<\/th>\n<th>Rome I provision<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Parties chose a law<\/td>\n<td>The chosen law governs the contract<\/td>\n<td>Article 3(1)<\/td>\n<\/tr>\n<tr>\n<td>No choice, service contract<\/td>\n<td>Law of the service provider&#8217;s habitual residence<\/td>\n<td>Article 4(1)(b)<\/td>\n<\/tr>\n<tr>\n<td>No choice, other contracts<\/td>\n<td>Law of the habitual residence of the party providing the characteristic performance, unless manifestly more closely connected elsewhere<\/td>\n<td>Article 4(2) and (3)<\/td>\n<\/tr>\n<tr>\n<td>Form, parties in the same country<\/td>\n<td>Valid if it meets the law governing the contract or the law of the place of conclusion<\/td>\n<td>Article 11(1)<\/td>\n<\/tr>\n<tr>\n<td>Form, parties in different countries<\/td>\n<td>Valid if it meets the law governing the contract, the law of a country where either party was present, or the law of either party&#8217;s habitual residence<\/td>\n<td>Article 11(2)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Formal requirements vary across the corridor. Spain requires every assignment to be in writing, and if the assignee fails to formalise it after a formal request, the author may terminate (<a href=\"https:\/\/www.boe.es\/buscar\/act.php?id=BOE-A-1996-8930\" target=\"_blank\" rel=\"noopener\">Spanish Copyright Act<\/a>, Article 45). In Mexico, transfers and licences not made in writing are void (<a href=\"https:\/\/www.diputados.gob.mx\/LeyesBiblio\/pdf\/LFDA.pdf\" target=\"_blank\" rel=\"noopener\">Federal Copyright Law<\/a>, Article 30). Brazil requires assignments always to be in writing (<a href=\"https:\/\/www.planalto.gov.br\/ccivil_03\/leis\/l9610.htm\" target=\"_blank\" rel=\"noopener\">Law 9,610\/1998<\/a>, Article 50).<\/p>\n<h2>What this means for your business<\/h2>\n<ol>\n<li>Put a governing law clause in every assignment and licence with authors, freelancers and agencies.<\/li>\n<li>Sign in writing even where the chosen law does not require it: it satisfies the strictest of the candidate laws.<\/li>\n<li>Audit oral or email-only arrangements with creators abroad, especially service providers whose home law would apply by default.<\/li>\n<li>In litigation, check standing early: a defendant may now attack the contract under its own governing law.<\/li>\n<\/ol>\n<p>Our <a href=\"https:\/\/ipglobalguard.com\/en\/services\/copyright-digital-works\/\">copyright assignment and licensing team<\/a> reviews and redrafts these contracts across Europe and Latin America, and our <a href=\"https:\/\/ipglobalguard.com\/en\/services\/legal-ip\/\">IP contracts and litigation team<\/a> handles standing disputes.<\/p>\n<h2>Where companies get cross-border assignments wrong<\/h2>\n<ul>\n<li><strong>Relying on oral deals with foreign creators.<\/strong> Without a choice of law, the creator&#8217;s home law may apply by default to a service contract, with its formal rules.<\/li>\n<li>Assuming the law of the market where you sell decides. After Steizer, it governs the infringement, not the validity of your title.<\/li>\n<li>Using one template everywhere without checking which law governs it and what form that law requires.<\/li>\n<li>Finding the defect in court, when a defendant challenges your standing.<\/li>\n<\/ul>\n<h2>Frequently asked questions<\/h2>\n<h3>Which law decides whether a copyright assignment needed to be in writing?<\/h3>\n<p>Following Steizer, the law designated by the Rome I Regulation. That is the law chosen by the parties or, failing a choice, the law determined under Article 4. Under Article 11, the contract is also formally valid if it meets the form rules of the place of conclusion or, for parties in different countries, of a country where either was present or habitually resident.<\/p>\n<h3>Does the ruling apply to contracts with authors outside the EU?<\/h3>\n<p>When an EU court decides the case, yes. Rome I applies the law it designates even if that is the law of a non-EU country, such as Mexico or Brazil. Courts outside the EU apply their own conflict rules, so a clear choice of law and written form remain the safest approach in the corridor.<\/p>\n<h3>Can IP Global Guard review our assignments with creators abroad?<\/h3>\n<p>Yes.
